Royal Observatory

Designed by Sir Christopher Wren in 1675, on the instructions of King Charles II, the Royal Observatory is best known as the location of the Prime Meridian. It represents Longitude 0º, with every place on Earth measured in terms of its distance East or West of the line, just as the Equator divides the Northern and Southern hemispheres. Flamsteed House, the original Observatory building, was named after the first Astronomer Royal, John Flamsteed, and contains the UK’s largest refracting telescope. During observing evenings in winter, visitors can view the night sky through the 28-inch telescope. It also houses two modern galleries, the apartments of the Astronomers Royal, and London’s only planetarium, which is much beloved by children and adults alike.
